Pipes, tubing and permeability
Published:  31 January, 2019

Pipes and tubing are ubiquitous and form the arteries of most equipment, machines and systems, yet all can suffer from the same problem - whatever is in them can permeate out. VERSAPERM says the solution is its latest range of vapour permeability testing.

Some materials allow thousands of times more vapour through than others and some, such as silicone, cellulose, EVOH and PVOH can be so poor at containing water vapour that they might as well not be there at all.

With Versaperm, measuring this permeability is said to be fast and very precise, allowing users to select the best materials, and refine the manufacturing process they use in their processes. This not only includes testing water vapour but also almost any other gas.
